California 155 connects Delano with Lake Isabella, crossing the Greenhorn Mountains along the way. It is a very winding and slow route due to the steep grades and construction designed to keep the road true to the contours of the landscape. At the east end, California 155 turns south at Wofford Heights to follow the west shore of Isabella Reservoir, connecting to the town of Lake Isabella and California 178 freeway.
Authorized in 1948 and completed in March 1953, Isabella Dam holds back water from the Kern River. This project was built to protect against downstream flooding, but it has ancillary uses for hydroelectric power and water supply for urban and agricultural use in the Central Valley. 10/08/06.

Eastbound SR 155 (Garces Highway) begins in the city of Delano at the RIRO ramps (Exit 56) connecting SR 99 with 9th Avenue. SR 155 follows the frontage streets to the freeway south four blocks to Garces Highway, which leads the route east from SR 99.

Authorized in 1948 and completed in March 1953, Isabella Dam holds back water from the Kern River. This project was built to protect against downstream flooding, but it has ancillary uses for hydroelectric power and water supply for urban and agricultural use in the Central Valley. While California 155 passes by the main dam, a second dam closer to California 178 holds back water as part of the Borel project.
